HENRY DAVIS OE BETHLEHEM, CONNECTICUT.

CARPET-SWEEPER.

Specification of Letters Patent No. 24,103, dated May 24, 1859.

To all whom it may concern:

Be it known that I, HENRYDAVIs, of Bethlehem, in the county of Litchfield and State of Connecticut, have invented a new and Improved Carpet-Sweeper; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, making a part of this specification, in which- Figure 1 represents a transverse vertical section of a carpet sweeper constructed according to my invention. Fig. 2 is an inverted plan of ditto.

Similar letters of reference, in both views, indicate corresponding parts.

This invention consists in arranging under the box of the swee er tw o r o ller ssparallel with the brush an so close to the sammm rotates sweeps agaihst the rollers, and that these latter serve a double purpose,to roll the box over the car et apd to assist tmtakih g u and throwing it into the box.

I o eiia ble those s kil'l'e'dfiwtl'ffir t td' fully understand; make and use my invention I will proceed to describe its construction and operation.

A represents a box constructed of wood, and in the usual form of boxes for carpet sweepers, forming a receptacle for the dirt as it is taken up by the brush, and leavingspace enough for the brush and the necessary rollers to work. The brush, B, is attached to an arbor, a, which has its bearings in two springs, b, and which passes freely through the slots, 0, in the sides of the box, so that it can rise and fall freely, and that by means of the springs, b, the brush is made yielding so as to bear down on the carpet at all times with the proper force.

7 Attached to each end of the arbor, a, is a pulley, C and both these pulleys connect by means of cords or belts, d, with grooved wheels, D; the grooves being made deep enough so that the belts do not interfere with the operation of these wheels as they pass over the carpet. These wheels are secured to the rear end of the box, A, and their faces project beyond the lower edge of the box so that the back part of the latter, when it is placed on the floor, rests on the wheels, D.

Arranged under the brush and parallel with the same are two rollers, E E, which extend through the whole width of the box, and which otate freel on their axles, c, whichmfiktmme box, and so close to the lower edge of the same that the rollers project beyond the edge of the box, and that the front part of the box rests 'on these rollers when it is placed on the floor. These rollers, therefore, rotate in the same direction in which the wheel, D, rotates when the box is pushed along on the carpet, and the belts or cords, (Z, are crossed so that the brush, B, rotates in the opposite direction to the rollers, E E, and these rollers are so close to the brush that the bristles of the same sweep against their surfaces.

The brush is protected by an arched piece of sheet metal or paste board, F, which is fastened to the front part of the box, and which extends down in front of the outer one of the rollers, E; and a scraper, G, is attached to the under part of the box as clearly represented in Fig. 2.

The operation is as follows :The box, A, is pushed over the carpet by means of a handle, in the usual manner, and the wheels, D, and rollers, E E, rotate in the direction of arrows 1, while the brush rotates in the direction ofarrow 2. The dirt taken up by the brush is drawn in between the same and the roller, E, which latter passes ir eelyover all dintamithoutcpnshing i t on one sid f so We can be reached by the bias-i alic the dirt is deposited in the box as the brush in its rotation strikes against the scraper, Gr, so that "the brush is completely cleaned, and by means of the springs, b, the brush bears down on the floor, at all times, with the proper force so that it takes up all the dirt.

What I claim as new and desire to secure by Letters Patent is The arrangement of the rollers, E E, to operate in combination with the yielding brush, B, and with the scraper, G, substan tially in the manner and for the purpose herein specified.
